WASHINGTON, D.C. – The National Park Service reports that they have finished a successful test using laser ablation to remove biofilm from the Thomas Jefferson Memorial. They say that test will pave the way for cleaning the rest of the memorial in time.

The test was conducted over the past four weeks and spanned 1,000 square feet of the over 10,000 square feet of the memorial. The Park Service says the results of the test will be visible to visitors once the scaffolding is removed from the dome of the Jefferson Memorial next week.

They also say the plan at this time is to continue using the laser ablation to remove the rest of the biofilm in 2018. It is part of a project to rehabilitate the Jefferson Memorial and is part of the 2018 budget.
